After reading the above three parameters, we need to know one important parameter which is the capacitor''s polarity.Since an electrolytic capacitor is polarised in nature, we can identify its polarity in the following ways:. By checking the polarity signs (+ or -) next to any one of the terminals. Connect ''+'' with the positive terminal and ''-'' with the negative one of the …
The basic idea of electrolytic capacitor types is to maximize the surface area of electrodes and thus increase their capacitance value and capacitance density. ... Therefore, in common standards, the measurement time is specified to be 5 minutes with rated voltage applied at room ambient (20 or 25 °C). Shorter times occur. Japanese ...

No! No, no no! It''s ESR that you need to measure, not capacitance. You MUST use an ESR meter to determine the "health" of an electrolytic capacitor. There are many available. You cannot determine the "health" of an electrolytic capacitor by measuring its capacitance.
Since this is consumer audio gear there is an easy way to figure out what voltage to buy when you don''t have the original spec. Choose the highest voltage that fits in the same space on the PCB. A higher voltage …

Short answer: No. A capacitance measurement will only give you part of the picture. You also need to measure the ESR, especially for electrolytic capacitors. You could have an electrolytic capacitor that measures exactly what its rated capacitance suggests, but the cap will not work at all in the circuit because its ESR is too high.
